JOSEPH V. GOULARDT, OF HAYVVARDS, CALIFORNIA.

ANlMAL-EXTERMINATOR.

SPECIFICATION forming part of Letters Patent It\To. 712,667, dated November 4, 1902.

Application filed April 16. 1902. Serial No. 103,209. (No model.) I

To aZZ whom, it rncty concern." Be it known that I, JOSEPH V. GOULARDT, a citizen of the United States, residing at Haywards, in the county of Alameda and State of California, have invented certain new and useful Improvements in Animal-Exterminators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. X

My present invention is an improvement in animal-exterminators; and it has for its objects to produce an exterminator which will possess all the requisites of strength anddurability and which will be especially simple in construction, efficient in operation, and capable of being readily cleansed or otherwise manipulated.

A further object of my invention is to make provision whereby the liability of clogging of the parts is reduced to a minimum, while danger from the accidental escape of the confined gases or liquid during the non-use of the device is obviated.

The process of extermination by the use of smoke as a medium is slow and objectionable, owing to its comparative non-poisonous action and the readiness with which it escapes through crevices in the ground. I have therefore constructed my invention with the idea of using carbon disulfid (CS as a medium whose fumes, besides having a specific gravity sufiicient to insure their settling in the burrows, have a marked and rapid destructive action on animal life. The parts are so arranged relatively that the accidental overturning of the device will not endanger the escape of the contents or its admission to other parts of the exterminator.

I am enabled to accomplish the above results by the means illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the complete device with a portion of the outer wall broken away to show the relative arrangement of the interior parts. Fig. 2 is a vertical section of the device on the line a: no of Fig. 3. Fig. 3 is a transverse section on the line y y of Fig. 2. Fig. 4 is a vertical section on the line 2 z of Fig. 3.

In the above views similar letters of reference represent corresponding parts.

The main body or holder of the device consists of a cylindrical reservoir A, made of galvanized iron and provided with a closed top B and a similarly-formed bottom C, the latter being positioned slightly above the bottom rim of the holder, while arranged transversely across the holder and at a short distance below the top B is the partition or deck D.

Above the top B and of a diameter greater than the cross-section of the holder A is the bellows E, which is supported in a rigid position relative to the holder by means of the three braces F.

Extending downward from one end of the bellows E and entering the top B at a point near the outer rim of the holder is the pipe G, while leading from the deck D and at a point ninety degrees around from the pipe G is the pipe H, which reaches to within a short distance from the bottom 0.

Protruding through the bottom 0 and in a line with the pipe G is the pipe I, the upper end of which almost reaches the deck D and is provided with the delicate spring-valve J,

whilethe lower end is closed by means of the cork K and is connected with the flexible hose L, the latter passing through the side wall of the holder.

The removable screw-cap M is positioned in the top B at a point directly above the pipe H, while throughthe side wall of the holder is the opening N, closed by means of a cap.

Of course it will be understood that a suitable valve 0 is arranged in the usual manner to admit the supply of air to the bellows, while the handle P and flexible bag Q are identical with those used on the ordinary fire-bellows.

I will now explain the operation of the device, assuming that the carbon disulfid in the form of a liquid is placed in the holder A. As the handle P is grasped and the bellows Q operated air will be forced through the pipe G into the upper part of the holder above the deck D, after which it passes through the large pipe H and bubbles up through the liquid, forming a vapor, which passes through the pipe I and finally to the tube L and burrow of the animal,therebyaccomplishing the speedy destruction of the latter.

By removing the cap M the interior of the pipe II can be readily inspected and cleared of any deposit, While by means of the valve J and relative arrangement of the pipes I and H, tube L, and handle P, should the machine be overturned, the liquid contents would be prevented from leaving the holder and gaining access to the interior of the pipes.

I am aware that changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made Without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations.

Vhat I claim as my invention is 1. An animal-exterminator consisting of a holder for the reception of the exterminating medium, a partition or deck near the upper portion of said holder, an air-bellows connected to said holder, a pipe leading from said bellows to said holder at a point above said deck, a secondary pipe leading from said deck to a point below the level of said medium, and a third pipe leading from said holder at a point above the level of said medium, substantially as and for the purpose set forth.

2. An animal-exterminator consisting of a holder for the reception of the exterminating medium, a partition or deck near the upper portion of said holder, an air-bellows connected to said holder, a pipe leading from said bellows to said holder above said deck, a sec ondary pipe leading from said deck to below the level of said medium, and a third pipe leading from said holder at a point above the level of said medium, and a valve positioned in said third pipe, said two latter pipes being arranged relatively as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOSEPH V. GOULARD'I.
